- How can time dilation be symmetric? 8 answers
if observer 1 sees observer 2 moving toward him at near the speed of light, observer 1 will say that his clock runs faster then observer's 2 clock, but observer 2 will see observer 1 toward him at near the speed of light, and observer 2 will say that observer 1 clock moves slower than his.
when they meet and compare clocks, what will the outcome be?
